There are two variations:
Variation A: Lift-truck has the early metal stick on signs that have SILVER "ROSS / TRAILOADER" lettering on a BLACK background.
Variation B: Late rubber-stamped in WHITE "ROSS / TRAILOADER" on the lift-truck sides.
Dimensions: 11 inches long, 8-5/8 inches wide, and base is 1-1/4 inches high.
The two trailers were available separately under the No. 460-150 and the middle classic box was labeled "No. 460-150 / TWO TRAILERS." There are three variations that are found on these trailers:
Variation A: WHITE Cooper-Jarrett vans that have COPPER signs. See: No. 6430.
Variation B: Fruehauf vans that are GREEN with metal side panels labeled "LIONEL LINES."
Variation C: Same as Variation A, except two GRAY vans.
Although the trailers are easily substituted, the No. 460’s that have been found only to have contained the GREEN "LIONEL LINES" labeled trailers (Variation B listed above). Since the Copper-Jarrett trailers were first sold in 1956, it is safe to assume that all of the No. 460’s were manufactured in 1955.
The trailers came with "Fruehauf" and "Duravan" labels that were applied to the front of these vans. Due to a printing error the SILVER lettering on the BLACK background is sometimes difficult to read. These tags are not found in later versions of these trailers except for the very first issues of the Cooper-Jarrett trailers in 1956.
